Abstract

A voice steel tap comprises a tap shell, a tap belt, a tap wheel, a tap spring and a brake device, and the edge, close to the lower portion of the tap shell, of the tap wheel is in a toothed wheel shape. An annular circuit board is arranged on the inner edge of the lower portion of the tap shell. An encoder, a single-chip microcomputer, a voice chip, a voice player, a battery and a power supply are all arranged on the annular circuit board. The encoder is arranged inside a tap belt pull-out opening, and is arranged in the middle of a small gear and coaxially rotates along with the small gear. The small gear is meshed with the toothed tap wheel. A voice player is formed in the portion, corresponding to the voice player, of the tap shell. The steel tap with the accurate reading function is developed by combining the advanced modernized electronic information technology with the automation technology, and the voice steel tap is simple, practical and particularly suitable for the environments where light rays are weak and vision can not reach. The technical content and the additional value of the steel tap product are increased, and the steel tap product is developed towards the high-tech aspects of automation, high precision, accurate positioning and the like.

Description

Voice steel tape

Technical field

The present invention relates to a kind of steel tape of voice reading, is a kind of voice steel tape that can automatic precision final figure specifically.

Background technology

Steel tape is a kind of instrument indispensable in house decoration, engineering decoration, building operation, daily life, is: measurement size is accurate to the performance requirement of steel tape, facilitates durable.And traditional steel tape function is simple, performance is single, with low content of technology; in measuring process, often can cause the phenomenon of misreading; even mark and cause because tape measure printing surface is not much numeral, such as, such thing in the time of tape measure typing equipment printing chi band, just run into.2008, Yucheng County's die making shop is that a measuring tool company limited has manufactured 5 meters of typing equipments, because tape measure in manufacture process is misread 10 centimeters of data, cause equipment body to be less than design standards and require 100 millimeters, result wheel is scrapped, renovation is reformed one month, more than 50,000 yuan of loss expenses of labour, fee of material.This phenomenon happens occasionally in routine use, and particularly, in building trade, door and window manufacturing etc., this phenomenon is the most outstanding.

Summary of the invention

The object of this invention is to provide a kind of voice steel tape that can automatic precision final figure, adopt hyundai electronics infotech, automatic technology to combine, exploitation has the steel tape of pin-point reading function, promote the technology content of steel tape product, realize steel tape product to new and high technology aspect development such as robotization, high precision, accurate location.

Realizing the technical scheme that the object of the invention takes is: it comprises chi shell, chi band, foot wheel, chi spring, brake gear, the foot wheel edge of adjacent bottom chi shell is gear-like, in bottom chi shell the inside, edge is provided with a ring-type wiring board, scrambler, single-chip microcomputer, speech chip, speech player, battery, power switch are installed on ring-type wiring board, scrambler is located at chi band pull-out mouthful the inside, be arranged in the middle of a pinion wheel, with pinion wheel coaxially together with rotate, pinion wheel engages with the foot wheel of gear-like; Brake gear is connected on power switch circuit; On chi shell, corresponding speech player is provided with a speech player hole.

Control circuit colleague technician of the present invention all can design, and is not described further at this.

Good effect of the present invention is: it is to combine by advanced Modern Electronic infotech, automatic technology, the steel tape with pin-point reading function developing, this tape measure operation interface close friend, simple and practical, be particularly suitable for using under the environment dark at light, eyesight is too late; Promote technology content and the added value of steel tape product, realize steel tape product to new and high technology aspect development such as robotization, high precision, accurate location.

Brief description of the drawings

Accompanying drawing 1 is embodiments of the invention structural representation.

Embodiment

The present invention as shown in Figure 1, comprise chi shell 2, chi band 1, foot wheel 12, chi spring 14, brake gear 15, foot wheel 12 edges of adjacent bottom chi shell are gear-like, in bottom chi shell the inside, edge is provided with a ring-type wiring board 13, scrambler 4, single-chip microcomputer 5, speech chip 6, speech player 7, battery 9, power switch 10 are installed on ring-type wiring board 13, scrambler 4 adopts stay-supported scrambler, be located at chi band 1 pull-out mouthful the inside, be arranged in the middle of a pinion wheel 3, with pinion wheel 3 coaxially together with rotate, pinion wheel 3 engages with the foot wheel 13 of gear-like; Brake gear 15 is connected on power switch circuit; On chi shell 2, corresponding speech player 7 is provided with a speech player hole 8.

Its principle of work is: pull-out chi band 1, foot wheel 13 drives pinion wheel 3 and scrambler 4 to rotate, taking the revolution of foot wheel 12 as basis, encoded device 4 carries out record to foot wheel 12 revolutions, the recorded single-chip microcomputer 5 that imports into carries out data reduction, and stores in speech chip 6, in the time pressing brake button 11, brake can trigger power switch 10, reads through speech player 7 numerical value that tape strip institute off-position is put.

the function of portions of electronics element of the present invention and parameter value:

One, single-chip microcomputer

The voice measuring control circuit of integrated ADC interface function in single-chip microcomputer, the data that dragline type scrambler and speech chip are transferred in single-chip microcomputer are processed, to reach the object of pin-point reading.

Two, speech chip technical parameter

1, apply simple and convenient, can be repeatedly erasable, the life-span is more than 10,000 times.

2, quiescent current is little, and tonequality is good, and operating voltage range is wide: 3V～5V

3, can select DAC output (external amplifying circuit) or PWM output (directly pushing away loudspeaker).

4, voice capacity is large, and from 80 seconds～10 hours, different time completely can be compatible.

5, keypress function is flexible, and 2 buttons, can trigger, and also can work as MCU control end.

6, sectional, the highlyest divides 999 sections.

Three, bracing wire encoder techniques parameter

Sensor with data readout bracing wire scrambler, output signal is square wave ABZ signal or gray code signal, and stroke maximum can be accomplished 10000 millimeters, and linear precision maximum can reach 0.05%, and resolving power can reach 0.01 millimeter/pulse according to the different maximums of configuration.Linear precision: (universal) 0.25%FS; (accurate) 0.05% ~ 0.08%FS; Repeatable accuracy: 0.01%FS～0.005%FS; Product form: current mode (4～20mA; Or 20～4mA); Voltage-type (0～10Vdc; Or 10～0Vdc) resistor-type (0～5k Ω; Or 0～10 k Ω); Impulse type (general 3600～5000 PPR, incremental) bracing wire scrambler useful life: 5,000,000 reciprocating strokes; Protection class: IP67 supply voltage: 24VDC(impulse type supply voltage: 5-24VDC).
